Specification of Letters Patent.

Application filed October 31, 1910.

Patented Nov. '7, 1911. Serial No. 590,033.

To all whom 'it may concern:

Be it known that I, HARRY Gr. GODLEY, a resident of Pittsburgh, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Wrenches; and I do hereby declare the following tobe a full, clear, and exact description thereof.

My invention relates to wrenches, its object being to provide a compact,strong wrench adapted to take hold on nuts of considerable size relativeto that of the wrench, and one in which the operative parts are entirelyinclosed within the body or handle of the wrench.

The wrench embodying the invention has a tubular metal body membercarrying one jaw and having in the upper portion thereof a square orlike angular bore or guideway to receive the like shaped angular body ofthe moving member carrying the other jaw of the wrench, and below thesame a cylindrical portion receiving a hollow cylindrical extension ofthe moving member, that extension being threaded internally and engagingwith the threaded operating bar which is confined within the wrench bodyby a supplementary sleeve which also serves to bind the handle on thewrench body, the wrench being operated by the turning of the inclosedthreaded bar through a suitable hand nut at the end of the Wrench.

In the accompanying drawing Figure 1 is a side view; Fig. 2 is alongitudinal central section thereof; Fig. 3 is a perspective viewpartly broken away of the body member; and Fig. 4 is a like view of themovable The main body member and the moving member of the wrench areforged to shape and suitably bored, for example, the main body member 2being formed of a bar slightly reduced in its lower portion 3 and havinga jaw 4 at its upper end. In the upper portion of this body member isthe square or angular bore or guideway 5, while below the same the boreis formed cylindrical as at 6. The moving member 7 of the wrench has thejaw 8 and is provided with the angular body portion 9 entering withinthe angular socket or bore 5 and has below the same the cylindricalextension 10 litting closely within the cylindrical bore 6 of the bodymember. The moving member yof the wrench is thus guided practicallythroughout the length of the body member .bot-h by the angular portionthereof and the cylindrical portion thereof litting withln like shapedguideways or sockets therefor within the body portion, and a long:angular body portion of the moving Imember can be employed which makesit possible to provide widely opening jaws 1n proportion to the lengthof the wrench Ebody, enabling the wrench to grip and hold inuts ofrelatively large size. The cylindrical extension 10 of the moving member7 jis formed hollow and has a long heavy gsquare thread cut within thesame as at 11 to engage with a like thread 12 on the screw :bar 18 whichenters within the tubular exitension 1 0 of the moving member andthrough its rotation within the handle or fbody nnparts movement to themovable jaw of the wrench. The threads of the screw bar 13 and tubularextension 10 are at a deep incline or what might be termed a doublepitch, so as to provide for quick fmovement and adjustment of thewrench, by a slight turning of the screw bar. lthreads are also squarecut so providing f square shoulders in the thread to sustain the thrust.threaded portion 12 the collar 14 and beyond the same the cylindricalportion 15 which ,l extends through the short sleeve 2O and carf riesbeyond the same the thumb nut 16 held thereon by any suitable means,such as by va tight threaded joint. 'reduced portion 3 of the wrenchbody is Ethe handle portion 17 which may be made of wood or othermaterial as desired, it-s inner edge iitting against t-he shoulders 18of the wrench body, while the handle has an The The screw bar 13 hasbelow its Fitting over the enlarged shouldered seat 19 at its end, and

` is held in place by the tube 20 which passes through the handle andscrews into the end of the reduced extension 3 of the body, the tubehaving the head 20 entering the seat 19 and so clamping the handlebetween the shoulder 18 of the wrench body and the head 20 of the tube.The tube 20 thus binds the handle upon the body portion, and its inneredge 21 forms an abutment to receive the thrust brought upon the collar1-1 of the screw bar 13 in the use of the wrench.

TWhen the wrench is in use, by turning the thumb nut 16 the movingmember 7 can be 'and as all the parts are inclosed within the handle acompact, strong wrench is provided in which all the parts are protectedfrom injury and the moving member is fully supported and guided nomatter what its position of adjustment may be within the body member. Byfit-ting the cylindrical eXtension 10 closely within the cylindricalguideway 6 the moving member of the wrench carrying the jaw is bracedbelow the angular portion thereof and the strain which has heretoforebeen usually sustained only by the angular portion and the angular seatin the body portion, is sustained throughout the length of the movingmember, such strain being distributed for a greater length throughoutthe wrench body, giving a stronger wrench construction and a morecompact one. The wrench has the further advantage that as the threadedconnection between the screw bar and cylindrical sleeve of the movingmember is entirely inclosed within the wrench body, liability ofclogging by dirt or the like is prevent-ed. It also has the furtheradvantage that it can be made to quickly grip any object such as a boltby but a slight turn of the thumb nut and as the wrench body is of butsmall diameter it can hold a nut to be adjusted in difficult positionsto be reached, such as in connection with automobile work and the like,so giving a very handy and easily adjusted wrench for such purposes. Ithas also the further advantage that the moving member is freelyremovable, such as for cleaning, or substituting a pipe jaw as shown inFig. 4 or for repair of the jaws.

What I claim is:

1. In a wrench, the combination with a body portion carrying a jaw, andhaving an angular socket and beyond the same a cylindrical extension, ofa moving member carrying a jaw having a like shaped angular bodyport-ion and a cylindrical sleeve extension itting closely within boththe angular socket and t-he cylindrical bore of the body and interiorlythreaded, a handle and a screw bar mounted to turn within the handle andhaving a threaded portion engaging with the threaded sleeve extension ofthe moving member.

2. In a wrench, the combination with a body portion carrying a jaw andhaving an angular socket and beyond the same a cylindrical extension, ofa moving member carrying a jaw and having a like shaped angular bodyportion and beyond the same a cylindrical sleeve extension fittingwithin the angular socket and the cylindrical bore of the body andinteriorly threaded, a handle tting overthe wrench body, a tube enteringthrough the handle and having a threaded engagement with the cylindricalextension of the body member and acting to clamp the handle between saidtube and the body member, and a screw bar mounted to turn within saidtube and having a threaded portion engaging with the cylindrical sleeveextension of the moving member.

3. In a wrench, the combination with the body portion carrying the jawand havingr an angular socket and below the same a cylindricalextension, a moving member carrying a jaw and having a like shapedangular body portion and a cylindrical sleeve extension fitting withinthe angular socket and cylindrical bore of the body and interiorlythreaded, a screw bar having a threaded portion engaging with thecylindrical sleeve extension of the moving member, said screw bar havingan annular shoulder, a handle fitting over the body member, and a tubeentering the outer end of the handle and engaging with the cylindricalextension of the body member to clamp the handle thereon and confine thescrew bar in place through said annular shoulder thereon.

In testimony whereof, I the said HARRY G. GODLEY, have hereunto set myhand.
